Cylindrical brushing machine

Abstract

The invention relates to the technical field of cotton seeds processing machinery, in particular to a cylindrical brushing machine. The cylindrical brushing machine is characterized in that: an outer cylinder (6) is arranged on the upper part of a frame (10); a rotary cylinder (15) is arranged in a cavity of the outer cylinder (6) and the circle centre of the rotary cylinder (15) is coincided with that of the outer cylinder (6); a steel wire brush (18) is arranged along the inner wall of the outer cylinder (6); the bristle points of the steel wire brush (18) form an inner circular working surface (14); an annular space (19) is formed between the inner circular working surface (14) and the rotary cylinder (15); scraping blades (17) with semicircular notches are arranged along the surface of the rotary cylinder (15); a feed port is formed on one side of the horizontal centre line of the outer cylinder (6), and a hair suction fan cover (7) is arranged on the other side of the horizontal centre line and opposite to the feed port; a discharge control device (11) is arranged at the rear end of the outer cylinder (6); and an automatically controlled feeder (1) is arranged above the outer cylinder (6). Compared with the prior art, the cylindrical brushing machine breaks through the technical bottleneck that the short hairs of the loose cotton seeds are difficult to clean, avoids excessive heat generated by the moving extruded cotton seeds and reduces the breakage of the cotton seeds at the same time.

Description

[technical field] [0001] The invention relates to the technical field of cotton seed processing machinery, in particular to a cylinder brushing machine. [Background technique] [0002] Seed cotton (seed cotton) harvested from the field is separated into two components, lint and cottonseed, after the ginning process. The lint is an important raw material for the textile industry, and the cottonseed is reserved for seeds. [0003] The important link of cotton seed processing is exactly delint, the method that cottonseed is separated (delint) from linter has two kinds of methods of chemical delint and mechanical delint at present. In the 1980s, my country introduced the sulfuric acid delinting method from the United States to process cotton seeds. Its working principle is to use strong corrosive chemicals such as sulfuric acid, penetrating agent, foaming agent and high-temperature baking to corrode the linters on the surface of cotton seeds. To achieve the purpose of fleece. ...

AI Technical Summary

Problems solved by technology

[0005] 1. Under the dual effects of high temperature baking and chemical corrosion, cotton seeds are easily damaged, and the quality of seeds is difficult to guarantee

[0006] 2. After chemical treatment, the linters on the surface of the cottonseed are all corroded, and the resources cannot be used

[0007] 3. A large amount of flue gas is emitted due to coal combustion. At the same time, chemicals such as sulfuric acid and penetrant volatilize to produce a large amount of corrosive acid mist, which has a great impact on the environment.

[0008] 4. The waste (acid and poisonous powder) produced by processing cannot be harmlessly treated. Whether it is incinerated or landfilled, it will cause harm to the environment and seriously pollute the atmosphere, soil, and water.

[0009] Since the 1990s, some cotton seed delinting machines with mechanical delinting methods have successively appeared in China. Due to design defects, this type of mechanical structure is unreasonable, the technical level is low, the process of delinting is too intense, and the cotton seeds are strongly squeezed and damaged. Serious, high seed temperature, high seed breakage rate, unsatisfactory delint effect, difficult to meet the quality requirements of cotton seed processing
